There are so many things to read and films to watch, it depends on whether you want to absorb a great deal or more or less walk through. Assuming you want to absorb as much as you can, I would break it down in the following way; Tom Hanks narrated movie (a little extra cost beyond admission) 48 minutes.....so about 1 hour taken up. The Europeon Theater 3 hours The Pacific Theater 2 hours So, I estimate 6 hours to try to soak it all up. It may be longer or shorter for some depending on individual pace. The museum is on two sides of the street. The Europeon Theater is in the building where you purchase tickets. The Hanks narrated movie (with special effects now) and the Pacific Theater is on the other side of the street. There is also a section on North Africa and Italy on that side of the street.

Not sure about senior but adults are only $11 pp.

I visited the museum in Oklahoma, and the one in Cherokee NC. Both are good. The one in North Carolina is better. So if you only go to one, pick North Carolina. If you do go, don't miss on the outside tour. They have a summer dwelling and a winter dwelling. Some archery and game skills are demonstrated. The gift shop and book selection is also good. Hope that helps.
